EXPOSURE


  • INHALATION
    		• Cough, nausea.
    		Local exhaust or breathing protection.
    		Fresh air, rest, and refer for medical attention.
  • SKIN
    		• Redness.
    		Protective gloves.
    		Remove contaminated clothes, rinse skin with plenty of water or shower, and refer for medical attention.
  • EYES
    		• Redness, pain.
    		Face shield.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
    		• Burning sensation, cough, nausea.
    		Do not eat, drink, or smoke during work.
    		Rinse mouth, do NOT induce vomiting, and refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING

    PHYSICAL DANGERS:
     Dust explosion possible if in powder or granular form, mixed with air.

    CHEMICAL DANGERS:
     The substance decomposes on warming producingcorrosive gas (hydrogen chloride - see ICSC # 0163). Reacts withstrongoxidants. Reactswith water and moisture producing corrosive fumes (hydrogen chloride).

    OCCUPATIONAL EXPOSURE LIMITS:
     TLV not established.


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body by inhalation andby ingestion.

    INHALATION RISK:
     A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20░C; if dispersing, however, much faster!

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance irritates the eyes, the skin, and the respiratory tract.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    PHYSICAL

    ENVIRONMENTAL
    DATA
    NOTES
    Reacts violently with fire extinguishing agents such aswater. Data are insufficiently available on the effect of this substance on human health, therefore utmost care must be taken.
